1) The host did not have their audio un-muted...The host can unmute their audio by right-clicking on their name (in the user-list) and selecting Unmute.

2) Push-To-Talk (a bit like a walkie-talkie) is enabled...By default, Push-To-Talk could be enabled for your Nefsis meeting.Try pressing (and holding down) the "Push-To-Talk" button at the top of the user-list while speaking.

In either case, you should see the person's name in the user-list highlight green when their talking.

Could you give us the manufacturer and model number of the device? The Nefsis client responds to left and right arrow input for changing slides in a presentation or document share, so if the device replicates this input or the device configuration software allows you to configure button presses to keyboard input this should be possible.

Hope this helps.

I'm trying to use a master Que slide advance system to control slides remotely in a conference room with Nefsis. I read in a previous post that the left right arrow keys are the key strokes that advance the slides. I can't seem to get the arrow keys to change the slides on the computer I'm using.

Is there a setting I have to change to enable that keystroke to react to the arrow key input? I can code my master que for that keystroke, but need to see it work on the keyboard 1st.

Make sure that the shared PowerPoint presentation has input focus (click the left mouse button on the slide visible in the shared region of Nefsis). Within the conferencing client, the arrow key function is based on the context of the window with input focus. Put simply: the action a key press initiates is based on what you are doing at the time.

Consider a situation where you share a PowerPoint presentation, then you share your desktop or an application. During the course of the desktop share, you press the right or left arrow to navigate or perform some action. It would be frustrating to you as the user if suddenly these buttons did not work as expected in the current context, but rather they change the slide of a PowerPoint thats not currently being viewed.
